My 1 month daughter is coughing while breastfeeding. She was doing well since the last week. But now, one of the breasts has overactive let down and I have tried laid down position. Yet, the baby chokes almost everytime I feed. Sometimes, she coughs and suddenly sleeps off peacefully. She seems okay while feeding from the other breast which has normal flow. What can I do? What if she is aspiring the milk?
